Description

The technical field to which the utility model relates.

The utility model relates to the field of transport and concerns the designs of amphibian snowmobiles used in search and rescue operations, by patrol services, for transporting goods and passengers to hard-to-reach places, for overcoming marshy areas, river spills, snowdrifts, shallow water, sandbanks, water bodies, overgrown with reeds and shrubs. Amphibian snowmobiles can be used by hunters, fishers and amateurs as a recreational vehicle.

State of the art

Known snowmobile amphibian (patent RU 2093407 publ. 20.10.1997) that contain a ski boat and mounted on it using shock absorbing elements, comprising a cabin and engine compartment with an engine and an associated propulsion device in the form of a propeller enclosed in a protective ring . The cabin is connected to the ski boat using two longitudinal parallel to each other and the plane of symmetry of the amphibian snowmobile, inclined to the horizontal of rigid rods, the front ends of which are pivotally connected to the rear wall of the cabin at its sides, and their rear ends are pivotally connected to the stern of the boat - ski, and a transverse inclined rigid draft, one end of which is pivotally connected to the bottom of the cabin on the side of one side, and the other end is pivotally connected to the ski boat from the opposite side. The device is equipped with two additional shock absorbing elements, with which the rear wall of the cabin along its sides is interconnected with a ski boat.

The closest technical solution to the proposed solution, chosen by us for the prototype, is an amphibian snowmobile, (patent RU No. 2082644, publ. 06/27/1997), containing a ski boat and a hull mounted on it. The ski boat is made with closed airtight compartments, the bottom of the ski boat has low deadrise and two longitudinal redans. The hull is mounted on a ski boat by means of one bow and two side feed damping elements. The bow shock absorbing element is installed in the diametrical plane of the ski boat, and two feed shock absorbing elements on its sides. Each of these shock absorbing elements is a twisted spring coaxial to the hydraulic shock absorber pivotally fixed by the ends respectively to the ski boat and the hull. The longitudinal axis of the bow shock absorbing element is located at an angle to the vertical and faces the top towards the stern of the ski boat. The longitudinal axis of the aft shock absorbing elements are vertical.

The disadvantage of these technical solutions is the complicated suspension system of the cabin and limited access during its repair and maintenance, as the cabin is placed inside the ski boat.

Limited operational capabilities are associated with the fact that when the snowmobile-amphibian moves in deep snow, problems with bends arise, since keeving will create a lot of resistance during bends. On ice, keel and redans are subjected to heavy loads, which leads to rapid damage to the bottom of the ski boat.

Utility Model Disclosure

The technical task of the proposed solution is to create a device with advanced functionality.

EFFECT: increased reliability of the body and reduction of shock loads of the body and bottom.

Common features of the known and proposed solutions are:

- ski boat,

- cab

- shock absorbing elements,

- motor and propeller.

The technical result according to the first embodiment is achieved by the fact that the hull of the ski boat is sealed, and the bottom of the ski boat is made flat and covered with protective material, while the shock absorbing elements, made in the form of four shock absorbers, consisting of a spring and a shock absorber, are installed in pairs on its flat surface in the bow and rear of the boat.

The technical result according to the second embodiment is achieved by the fact that in the ski boat there is a recess in which the lower part of the cabin is placed, the body of the ski boat is sealed, and the bottom of the ski boat is made flat and covered with protective material, while the shock-absorbing elements made in view in four suspension struts consisting of a spring and a shock absorber and are installed in pairs in the bow and rear of the boat.

Due to the suspension struts, the vertical forces acting on the ski boat cause only cabin vibrations, which protect the hull of the boat and skis and cabs from damage and deformation.

Performing the bottom of the boat-ski flat and covered with protective material allows you to protect against impacts on the ground or ice.

The analysis of the prior art by the applicant, including a search by patent and scientific and technical sources of information and identification of sources containing information about analogues, suggests that the proposed solution meets the requirement of "novelty."

It should be noted that the advantage of the utility model over a close analogue (prototype) is provided by the presented set of essential features, each of which performs its own function, and together, in conjunction, they solve the problem of creating a new one that meets modern design, technological requirements.

Brief Description of the Drawings

The utility model is illustrated by drawings.

In FIG. 1 shows a general view of an amphibian snowmobile, made according to the first embodiment; in FIG. 2 amphibians, shows a General view of a snowmobile-amphibian made in the second embodiment.

Utility Model Implementation

The amphibian snowmobile is a ski boat 1 connected to a cabin 2. Cabin 2 is connected to a ski boat 1 using shock absorbers consisting of a spring 3 and a shock absorber 4. The ski boat 1 is made of lightweight, durable materials such as aluminum fiberglass. Cabin 2 is made of aluminum frame and aluminum cladding. The bottom of the ski boat 1 is made flat and covered with a protective material 5. Plastic of various modifications and other similar materials can be used as a protective material. Cabin 2 is made of aluminum frame and aluminum cladding. The frame of the cab 2 is a spatial frame assembled from an aluminum profile of various sections. Engine 6 is mounted on the carcass frame 2 with propeller 7 and air controls 8. Engine 6 is closed by a hood, and propeller 7 is closed by a grill for the safety of people.

The ski boat has a minimum side height, the height of the sides is slightly higher than the level of the water line with a full curb weight of amphibian snowmobile. Performing the bottom of the ski boat 1 with a flat surface allows the snowmobile to move well and turn not only in water but also on snow, ice and soil.

When moving along an uneven track, the light ski boat 1 (its mass is 20% of the mass of the amphibian snowmobile), like a car wheel, tracks the relief of the track (or water waves), perceives shock loads from the roughness of the track and transfers them through the spring suspension to the cabin .

The proposed solution allows to increase the reliability of the hull and reduce by 5 times the shock loads of the hull and bottom.

Navigation of this vehicle can continue year-round, even when lakes and rivers are covered with thin ice.

Currently made prototypes of the claimed utility model, and so on. The real possibility of its implementation with the help of the described means and methods is confirmed, ensuring the technical result perceived by the applicant.

Therefore, the claimed utility model meets the requirement of "industrial applicability".
